What we do with the most personal thing you own
Cortex asks for your writing, your voice, your history, and sometimes your screen. That is a lot to hand anyone. This page tells you exactly what happens to it, including the parts that are not flattering to us.
What we collect
Only what you give us, plus what you explicitly connect:
- Text, files, and documents you upload.
- Voice recordings you make, and their transcripts.
- AI chat exports and social exports you choose to import.
- Data from accounts you connect (Google Calendar, read-only), and only the capabilities shown to you at the time you connect them.
- If you install Cortex for Mac: screen and audio context, which is opt-in, separate, and can be paused at any time.
We do not buy data about you, and we do not scrape you from the open web.
Who can see it
Your brain is private by default. New accounts are not public, your clone answers nobody until you turn it on yourself in Settings.
Here is the uncomfortable part, stated plainly: Cortex is not end-to-end encrypted, and we are not going to pretend otherwise. The whole product works by retrieving over your corpus on our servers, which means our systems can read it. Your data is encrypted in transit and at rest by our infrastructure provider, and access is restricted to a small number of people, but “we cannot see it” would be a lie, so we do not say it.
What we do instead is make every privileged access visible to you. Cortex support can repair a brain when something breaks. Every time that happens it writes a row to an append-only log that you can read in Settings → Your data. That log cannot be edited or erased from inside the product, including by the person it names.
What we send to model providers
Cortex uses OpenAI and Anthropic models to build and run your clone. Requests carry the parts of your corpus needed to answer. Every OpenAI chat request is sent with storage switched off (store: false), enforced in code on each request.
What that does not cover: we have not signed zero data retention agreements with OpenAI or Anthropic. Under their standard API terms they may keep request data for a limited period for abuse monitoring. When those agreements are signed, this page will say so.
Your data is never used to train those models. That is true both because we do not send it for training and because the API terms of both providers prohibit it.
How long we keep it
We keep what your clone needs, not the originals. Voice recordings are deleted as soon as they are transcribed. The full original text of anything you add is deleted a day after it is processed. What stays is the passages your clone searches and quotes, and what was learned from them. Recordings made to build your voice clone are kept until the voice is made, and never longer than 7 days; rebuilding it later means recording again. You can reset your brain, which deletes every source and everything derived from it, or delete your whole account.
How to leave
Export. One file containing every source, note, memory, chat, and artifact in your brain, plus download links for any recordings we still hold. It is plain JSON, readable, and portable to anything you want to move to.
Delete. Your account locks immediately and your public clone goes offline the moment you confirm. Seven days later everything is permanently destroyed: sources, memories, chats, transcripts, recordings, your cloned voice at our voice provider, API keys, and connected accounts. The seven days exist so a moment of frustration, or someone else getting into your account, is recoverable. You can cancel any time before the deadline.
Two things survive on purpose: your username stays reserved so nobody inherits your public clone URL, and billing records are kept because they are financial records. No personal content remains.
Both live in Settings → Your data.
The provenance firewall
Cortex separates what you said from what merely happened around you. Content from third parties, ambient capture, or connected accounts can help your clone answer a question and is always attributed, but it can never merge into your own memory or shape your profile, your identity model, your judgment, or your voice.
Practically: a colleague’s opinion in an email thread you imported will never become something your clone believes. Device and connector data is also excluded entirely from your public clone, so anything ambient stays between you and your own brain.
Company Intelligence
Company Intelligence is a separate product: the company's files and systems, queryable, with permissions. It is not a clone of your people. Cortex still clones experts. These answers are for a US buyer evaluating the company product.
- Is our data mixed with other companies? No. Every row is keyed to one organization. Retrieval never searches across tenants.
- Do you train models on our data? No. Every OpenAI chat request is sent with storage switched off (store: false). Company content is not used to train our models or a provider's.
- Encryption in transit and at rest? Yes, by the infrastructure provider (TLS in transit, encrypted disks at rest). We are not end-to-end encrypted. Retrieval has to read the corpus on our servers.
- Who can see what? Role-based access plus the source ACL. A restricted space is invisible to anyone without a grant, including an admin who was not granted it. Cross-user retrieval never includes agent-private memory.
- Can we delete everything? Yes. Organization admins can revoke sources. Account deletion still purges a person's grants. Company documents belong to the organization until that organization asks us to destroy them.
- Will this pass Vanta / SOC 2? Not yet. We do not hold a SOC 2 report today. Tenant isolation, RBAC, source ACL, no-training, and store: false on OpenAI calls are true now. Formal SOC 2 is on the path; if you need it for procurement, tell us and it moves up.
Identity for the October cohort is Google Workspace login plus organization membership. SSO and SCIM are available on request for enterprise customers; see Security.
What we are still working on
Being straight about the gaps, because you should be able to price them:
- We do not yet hold a SOC 2 report. If you are evaluating Cortex for a company and need one, tell us, it moves up the list based on who asks.
- Per-user encryption keys, which would narrow our own access further, are not implemented.
- Retention controls are all-or-nothing today. Per-source retention windows are planned, not shipped.
